Almost all competitive intelligence aims at what’s public: the site, social media, the ads in the Meta Ad Library. But a huge slice of selling happens where no outsider can see — in the1-to-1 channels: WhatsApp and email. That’s where a competitor fires off the flash offer, the cart-recovery coupon and the launch alert. Anyone who doesn’t monitor these channels has a blind spot the size of the channel that converts best.
And it’s not a minor detail: in Brazil, WhatsApp has become the sales counter.

Why email still matters (a lot)
If WhatsApp is the counter, email is the repurchase machine. With ROI estimated between US$ 36 and US$ 45 per dollar invested in retail, it’s the most profitable channel there is — and, unlike WhatsApp, it’s the easiest to monitor: just subscribe to your competitor’s newsletter. The detail that separates the amateur from the pro is watching the automation, not just the mass campaigns.

What to extract from each channel
Monitoring a 1-to-1 channel isn’t about volume; it’s about reading the intent. Every message carries cadence, offer, segmentation and copy. Here’s what to look at:
| Channel | What to extract | How to access | Frequency |
|---|---|---|---|
| Email / newsletter | Send cadence, offers, automated sequence, segmentation, copy | Subscribe with a dedicated email | Continuous |
| WhatsApp / broadcast | Send frequency, flash offer, catalog, tone of the approach | Opt in to their public list | Weekly |
| SMS / push | Urgency triggers, cart recovery | Public opt-in when available | Biweekly |
| Loyalty program | Points structure, benefits, repurchase triggers | Public sign-up | Monthly |
How to set up the capture in 4 steps
Step 1
Create a dedicated email
An address just for competitive intelligence, separate from operations.
Step 2
Subscribe to your 3–5 direct competitors
Newsletter, WhatsApp and any public list they publicize.
Step 3
Record cadence and offers
When they send, what discount, which trigger. The pattern shows up within weeks.
Step 4
Cross-reference with the public channels
Does the email offer match the ad and the site price? That’s the whole strategy.
